Q1: Is CZ318 suitable for carbonated drink bottles?
A: Yes. Its Intrinsic Viscosity (I.V.) and high mechanical strength make it ideal for high-pressure Carbonated Soft Drink (CSD) packaging.
Q2: Does PET CZ318 require drying before processing?
A: Yes, pre-drying is mandatory. Failure to dry the resin properly can lead to hydrolysis, which significantly degrades the material’s physical properties.
Q3: Can it be used for food packaging?
A: Yes, it is a food-grade resin that complies with international safety standards, including FDA and other food-contact certifications.
